Self-leveling compound Vs Mortar

We will explore the key characteristics of self-leveling compound and mortar, highlighting their similarities and differences.

Comparison: Self-Leveling Compound vs. Mortar

Now that we have explored the characteristics of self-leveling compound and mortar, let’s summarize the key differences between the two:

  1. Consistency: Self-leveling compound is more fluid and self-leveling, whereas mortar is denser and requires manual shaping and leveling.
  2. Usage: Self-leveling compound is suitable for filling smaller voids and creating a level surface for flexible flooring. Mortar, on the other hand, is used to fill in more voids and patch up damage in a variety of flooring.
  3. Composition: Self-leveling compound contains a blend of cement, polymers, and fine aggregate, while mortar consists of cement, sand, water, and aggregate.
  4. Application: Self-leveling compound is poured onto the floor and spreads evenly on its own. Mortar requires manual application, leveling, and shaping using a trowel or similar tools.
  5. Surface Compatibility: Self-leveling compounds can be applied on various substrates, including concrete, wood, and tile. Mortars are commonly used in applications such as setting tiles, filling gaps, and repairing cracks in concrete.
  6. Vertical Surfaces: Self-leveling compounds are not suitable for non-horizontal surfaces or vertical walls. Mortars can be applied on vertical surfaces, making them more versatile for specific repair needs.
  7. Strength: Mortars offer excellent durability and can withstand heavy loads, making them suitable for high-traffic areas. Self-leveling compounds are designed for leveling purposes and provide a stable foundation for flexible flooring.

Self-Leveling Compound

Self-leveling compound, also referred to as resurfacers or slurries, is a specialized material used for leveling uneven or damaged flooring surfaces. It is a fluid mixture that has a low viscosity, allowing it to flow and level itself out. The compound is typically composed of a blend of cement, polymers, and fine aggregate.

One of the primary advantages of self-leveling compounds is their ability to create a smooth and level surface. They are particularly effective in filling smaller voids and shallow cracks, providing a seamless foundation for various types of flooring. Additionally, self-leveling compounds can be applied over a variety of substrates, including concrete, wood, and tile.

Using self-leveling compound involves a straightforward process. First, the surface is thoroughly cleaned and prepared to ensure proper adhesion. Then, the compound is mixed with water to achieve the desired consistency, following the manufacturer’s instructions. The mixture is poured onto the floor and spread evenly using a trowel or gauge rake. The compound then self-levels, eliminating the need for extensive manual leveling.

It is important to note that self-leveling compounds are not suitable for non-horizontal surfaces or vertical walls. Due to their fluid nature, they are unable to maintain their shape on inclined or vertical substrates. Additionally, self-leveling compounds may not cure well in areas exposed to heavy machinery or harsh chemicals, as these factors can interfere with the curing process.

Mortar

Mortar, on the other hand, is a more traditional material used for various construction applications, including flooring repairs. It is a mixture of cement, sand, and water, with the addition of aggregate to provide strength and thickness. Mortars are generally denser and less fluid compared to self-leveling compounds.

Unlike self-leveling compounds, mortars are not designed for leveling or patching floors. Instead, they are mainly used for filling deeper voids and repairing damaged areas in the flooring. Mortars offer excellent durability and can withstand heavy loads, making them suitable for high-traffic areas. They are commonly used in applications such as setting tiles, filling gaps, and repairing cracks in concrete.

The application process for mortar involves several steps. First, the surface is cleaned and dampened to ensure proper adhesion. Then, the mortar is mixed according to the manufacturer’s instructions, taking into account the desired consistency. The mixture is applied to the prepared surface using a trowel or a similar tool. Mortar may require manual leveling and shaping to achieve the desired result.

While mortars are versatile and widely used, they are not recommended for creating a level surface or filling shallow voids. Their thicker consistency makes them less suitable for achieving a smooth and seamless finish. Therefore, mortars are typically reserved for projects where leveling is not the primary objective.
